Procedure details

An unmanned free balloon ("weather balloon") may only be operated with the permission of the state in which the ascent takes place. Prior permission must therefore be obtained from the competent aviation authority for the release of unmanned free balloons.

The following information must be provided to the aviation authority:

  • Technical data of the balloon
  • Classification of the balloon (light/ medium/ heavy)
  • Number of payload packages
  • Launch location (coordinates)
  • Release period (date/time)

An unmanned free balloon may only be operated if persons or property are not endangered when the balloon or part of it, including the payload, hits the earth's surface.

  • Consent of the landowner of the site of admission

30.00 to 500.00 EUR

The costs are calculated on a case-by-case basis depending on the complexity of the matter.

The application should be submitted at least 10 working days before the first planned release date.

Unmanned free balloons can be divided into different classes depending on their weight and payload (light, medium and heavy). Depending on the total mass and place of ascent of the free balloon, it may be necessary to obtain an air traffic control clearance from the responsible air traffic control center in addition to applying for the permit.
